Q&A - PSLE Math

Michaelia0816:
Why must be divided by 2? I tried to divide it but cannot get the answer, I was struck at this statement at my HW.
Hi
In the end, the number of boys at the party became thrice the number of girls.
Boys:Girls ------- 3:1
In MD format, we’ll have 3 boxes to show the number of boys and 1 box to show the number of girls.
The difference is 2 boxes or units.
2 units ------ 60
1 unit ------ 30

Ok, I get the answer already, Thanks!

Michaelia0816:
For my Q2, my statement is the same bit I did not stop at 14,I times it, my big mistake!
Hi
The brutal truth is that mistakes would be made now and then.
It’s better to make it now in this forum and learn from it rather than the actual PSLE exam.
You’re a bright young girl; you should be able to tackle the challenges ahead of you.

Ok , I almost needed to use GC, But my teacher told me in class yesterday that got a heuristic way!
Hi girl
Do not forget that GC is also one of the heuristics in primary maths syllabus.
